It has been proposed that the
dividing of the earth in the days of Peleg was caused by the covering of
land bridges at the end of the last ice age. The scientific data indicates
that the temporary land bridges between continents were covered completely
by 11,000 years ago.1 Peleg is derived from the
Hebrew word palag, which means “divide” or “divided”. This
word occurs 4 times in the Old Testament. Twice it refers to the Sons of
Eber (Genesis 10:25 and 1 Chronicles 1:19).2 A third time, it refers to
making a channel from a flood (Job 38:25)3 and the fourth time it refers to
the confusion of the speech of the wicked (Psalm 55:9).4
The use of the word Peleg in reference to creating a channel from a flood
suggests that God might have used the melting ice from the last glaciation
to remove the land bridges to separate the major human populations.
